Green Lantern Jessica Cruz VS Bolphunga
Bolphunga was the idiot who challenged the Green Lantern Mogo to a duel because he heard of the latter’s reputation as a strong warrior. Bolphunga the Unrelenting landed on the planet supposedly inhabited by Mogo and hunted him for weeks. He then realized after awhile that Mogo was actually the planet itself.
